audio not working after Mojave update on 2015 MB Air

I updated to Mojave and the internal speaker are not seen, nor is the internal microphone seen. I can hear audio with bluetooth headphones and on Airplay on the TV. I have uninstalled and reinstalled the OS. I have plugged headphones in and it does not see them either. I have done a PRAM and all other resets without any change. I have a late 2015 MacBook Air. Does anyone have a fix for this? I can hear the "chime" every time I reload the OS, but once it is loaded...nothing in the settings showing internal speakers or microphone.

MacBook Air (13-inch, Early 2015), macOS Mojave (10.14), sound

I contacted Apple support on chat, and here is what worked for me.

go to this folder /Library/Preferences/Audio

and move these 2 files to trash

com.apple.audio.SystemSettings.plist

com.apple.audio.DeviceSettings.plist

then shut down and do a PRAM reset
